Specification of Letters Patent.

Application filed January 28, 1914. Serial N 0. 814,931.

To all whom it may concern:

Be it known that I, BERTHA S. ALsoP, a citizen of the United States of America, and residing at New York, in the county of New 6 York and State of New York, have invented new and useful Improvements in Bottles, of which the following is a specification.

My invention relates particularly to the valve construction of what are commonly 10 termed non-refillable bottles.

ile it is possible to construct a bottle which cannot be filled under any circumstances commercial difiiculties are such that it is ver expensive. For ordinary pur oses 1 it is su cient if the bottle cannot be re lled by the ordinary methods. Most of such con- I structions however, can be partially filled or filled with difficulty and slowly by the use of pressure.

It is my main object to provide a simple and inexpensive construction which is substantially non-refillable under ordinary conditions and which cannot be emptied in case it has been subjected to treatment which has refilled or partially refilled the bottle. This is accomplished by the use of a valve which consists of two parts, a body and a flexible seal. Means are also provided for preventing mechanical access to the valve or valves 80 for the purpose of manipulation. When the bottle is tipped up to pour out the liquid, the valve automatically opens by gravity and the pressure of the liquid. When the bottle is stood upright the valve closes automatically by gravity. When it is attempted to force the liquid into the bottle under pressure, the valve is forced backward against a stop and locked by the flexible seal so that the valve will not open again. This prevents the pouring out of any liquid which may have been forced in, and consequently prevents the re-use of the bottle after it has been once emptied.

Figure 1, shows a cross section of the neck of a bottle embodying one form of the improvements of my invention. Fig. 2, is a View similar to Fig. 1 but with the bottle tilted in the pouring position. Fig. 3 is a view showing the several parts which oo- 80 operate to form the bottle closure, the parts being shown separated. Fig. 4, is a bottom lan view of the movable guard member. Fig. 5, is a bottom plan view of the valve member. Fi 6, is a top plan view, of the 65 same. Fig. is a fragmentary sectional vguard,

yiew showing how the valve is looked after it has been forced back by pressure, the guard and other parts being omitted in thisview. Fig. 8, is a sectional view of the neck pf the bottle in another form of my inven- As above indicated, the valveconsists of two parts, the body 10 of some material such as glass or porcelain, and a thin flexible seal 11 which is secured to the body and extends beyond the edges of the body so asto coact with the valve seat. This seal may be made of suitable material which is unaffected by the liquid contained in the bottle and which will not affect the liquid.

The edge of the valve body is preferably corrugated or fluted as shown at-12 and fits loosely within the passage 13 in the bottle neck 14:- The edge of the seal 11 normally seats on the shoulder 15, at the outer end of passage 13. The outward movement of this valve is limited by the movable guard member 16, and the inward movement if limited by the shoulder 17. The ball 18 is provided for assisting in holding the valve in its closed position. The movable guard, the ball and the valve are all inclosed within a casing 19, which, as shown, may be in the form of a cap, provided with a central pouring outlet 20, and secured to the bottle neck by a retaining ring 21.

A tortuous passage for the liquid, is provided by grooving the sides of the movable as indicated at 22, so as to force the liquid to flow along the sides and across the top of the guard to the pouring mouth or outlet. The top of the guard may be dished as indicated at 23 to afford a large air space and to make more difficult the insertion of an instrument in the outlet grooves. ball 18 is located ina recess 24 in theunderside of the guard 16, said recess having an inclined wall 25 which, as will be clear from Fig. 2 will have a tendency to force the ball over to close the valve except when the bottle is fully tilted.

When the bottle is tilted, the valve moves outward slightly and the liquid passes through the flutes 12 and out from under the seal 11. When it is attempted to refill the bottle, the valve is forced inward and the edges of the seal 11 are thereupon engaged beneathvthe shoulder 27 in the passage 13 so that it will thereafter be impossible to pour out the liquid. This shoulder 27 may no The 95 be formed by a separate washer .Z'Y'asdshOWn in Fig. 7. The guard is preferably provided with one or more notches 22 forming air passages leading to the valve so that air may immediately flow to the valve to force it into its locked position in case air pressure issuddenly applied.

To prevent the valve from being drawn outward by suction, I may provide a central passage 28 through the body 10 of the valve and a small tongue 29 in the seal which is adapted -to be drawn outward by suction which would otherwise be sufficient to draw out the valve. Suction will therefore lift the tongue 29 and thus prevent the valve from being drawn outward. The seal issufficiently stiff to spring back and close the opening as soon as the suction ceases. In

most cases the body of the valve may be imperforate as shown in Fig.

In the form of the invention shown in Fig. 8, the body 10 of the valve is provided with pivotal means such as pivots 30, 30. The valve is carried by an interior portion, consisting of the two halves 31 and 32 for convenience in manufacture and these parts are held in the neck 14: of the bottle. The valve is pivotally carried by a partition 38, the edge of which forms one edge of the valve seat, the other edge being formed by the ledge 34:. The open movement ofthe valve is limited by a stop 36. Another stop 37 is provided to limit theinward or backward movement in case an attempt is made to force the valve inward under pressure. Another valve 38 of construction similar to that just described, is provided in the construction illustrated in Fig. 8 with stops 36 and 37. It will be noted that the axes of these two valves lie in the same vertical plane but are inclined relative to each other and that the seats of the valves are inclined in opposite directions. Suitable means are provided to prevent access to the valves such for instance, as partitions 40, 41 and 42. An opening 44: is provided at one side for exit of the liquid. The valve carrying parts may be secured in place by means of a resilient clip (not shown) arranged to fit in a groove as in the valve supporting member and a corresponding groove in the inside of the bottle neck in which the support is inserted. The valves are so arranged and constructed that it is impossible to fill the bottle except by the application of considerable pressure. When pressure is applied however, it forces the valves inward or backward, for instance, the edge of the valve 10 will be forced inward and strike against the stop 37 but some liquid may leak past the valve. This drives in with it the outer edge of the seal 11 which is thus interposed back of the ledge 34. If it is now attempted to pour out the liquid which may have been forced in, this engagement of the seal 11 with the under side of the ledge 34: will prevent the valve from opening and the bottle cannot be emptied.

It is obvious that no one who is familiar with the peculiarity of this locking valve construction will attempt to refill the bottle and there is no danger that a bottle which has been refilled will be used to supply a substitute for the original liquid.

What I claim is 1. In a bottle, a valve seat surrounding a liquid passage, a valve for said passage comprising a body located in said passage and a flexible seal extending'over the outer edges of said body and said seat, astop for limiting the inward movementof said body and a shoulder for coacting with said seal to lock said valve when the valve has been forced inward.

2. In a bottle, a valve seat surrounding a liquid passage, a valve for said passage comprising a body located in said passage and a flexible seal extending over theouter edges of said body and saidseat, a'stop for limiting the inward movement'of saidbody, a shoulder'for coacting with said seal to lock said valve when the valve has been forced inward and means for preventing mechanical access to said valve.

3. In combination, a bottle provided with an outlet passage, a valve normally closing said passage and arranged to open outwardly to permit pouring of the contents of the bottle and means rendered operative by external force applied to said valve for preventing subsequent opening movement of the valve.

4- In combination, a bottle provided with an outlet passage, a valve controlling said passage, normally opening outwardly to permit pouring of the contentsof the bottle and displaceable by the application of force thereto to open inwardly intothe bottle and means'cooperating with said valve after the same has been forced inwardly to prevent any subsequent outwardly opening movement ofthe valve.

5. In'combination, a bottle provided with an outlet passage, seats surrounding said passage and facing in opposite directions, and a valve normally engaging the outer one of said seats and displaceable by the application of force thereto into operative relation with respect to the inner seat.

6. In combination, a bottle provided with an outlet passage, a valve normally closing said passage and opening outwardly to permit pouring of the contents ofthe bottle, means preventing mechanical access to the valve and means rendered operative by external pressure applied to 'the'valve for preventing subsequent opening movement of the valve. V

7. In combination, a bottle provided with a liquid passage, a valve seat surrounding said passage, a valve body engaged in the said passage, a stop limlting the inward movement of the valve body Within the passage and a flexible seal carried by the valve body, extending beyond the outer edges of the valve body to thereby normally rest upon the surrounding valve seat and adapted upon application of pressure to the valve to be carried by the valve body down into the passage and into engagement with the 10 Walls of the passage at a point below the valve seat.
